Highlights

The development of improved fish seed stocks that can contribute to increased fish production while ensuring protection of biodiversity and the environment is seen as one of the key solutions to meeting the future food demands of the growing world population
Some 3 min after fertilization, the success of triploidy was determined by the presence or absence of bent trunk in the fry as reported by (Aluko et al, 1997)
Induced triploidy is used to produce partially or completely sterile fish, whose 3 chromosome sets impair the meiotic division involved in germ cell formation (Thorgaard and Allen, 1987; Chourrout, 1988; Levanduski, et al, 1990)

Summary

Introduction

The development of improved fish seed stocks that can contribute to increased fish production while ensuring protection of biodiversity and the environment is seen as one of the key solutions to meeting the future food demands of the growing world population. Genetics and the successful application of breeding programs in crops and livestock have provided the impetus for the governments in developing countries opportunities to and quickly increase food production. Current interest in polyploidy induction is almost entirely due to its potential application in fish farming, for the pro-duction of triploid and tetraploid fish (Purdom, 1993; Pandian and Koteeswaran, 1998). The energy, which would normally be directed for gonadal growth (gonad formation) and reproduction, is used for somatic growth (Pandian and Koteeswaran, 1998)
